exclude the entrance of air and dust beneath the door under allconditions of working and weather.

A further object of the invention relates to the provision of adust-guard for covering the opening under one member of theweatherstrip.

Still further objects of the invention relate to details of constructionand to combinations andoperations of parts, all as hereinafter fully setforth.

In the simpler forms of weathenstrips, material such as rubber or felt,is secured on the bottom of the door to the thickness necessary to fillup the space between the bottom of the door and the surface of the sill.The constant friction between this material and the sill soon wears theformer away, so that the entrance of dust and air is no longerprevented, and there is no way of compensating for this wearing away,except by securing additional material to the bottom of the door,.

which is not only troublesome, but is apt to render the door unsightly,material secured on the door, if the latter be an outside door,frequently becomes wet and freezes to the sill and is torn oil when thedoor is opened. This objection applies also to practically all forms ofweather strips affording direct contact with the sill and in whichmaterial other than metal is employed. Attempts have been made toprovide weatherstrips which shall automatically compensate for wear byproviding springs for pressing the strips into contact with the sill,which springs are either normally operative,

- or are brought '1'" operation by the operation of closing the door.All such devices are 0 ion to the objection of expense and trouble ininstallation, of liability to injury, and of danger of' the springsrusting and breaking after use for some time.

My invention aims to overcome these and other objections, by providing asubstantially all-mctal weather-strip, one member of In addition, the

L which is carried by the door and the other by the sill, and thecontact between which parts when the door is closed is direct andpositive, as opposed to frictional, or sliding, 6 and yielding.

In the drawings: Figure 1 is a broken f ace view, showing a door andsill having my invention applied thereto, the door being closed, and aportion of the 1\'( ittll01-StI'lp 6 being broken away to betterillustrate t-he construction. Fig. 2 is a perspective view on anenlarged scale, showing one end of the sill member of the weather-stripwith a plate carried by the door resting thereon, the door 7 beingbroken away and sectioned. Fig. 3 is a cross section, also on enlargedscale, through the door sill and the lower portion of the door. Fig. 4is a sectional view taken on a line passing between the front edge ofthe door and the door frame. Fig. 5 is a perspective view of a portionof the weather-strip memher which is designed to be secured to the door,the full lines showin the normal shape and the dotted lines the s apeafter it is apstrip secured onthe door sill. Fig. 7 is a horizontalsectional view on the line 7-7 of Fig. 6, but on an enlarged scale. Fig.8 is a section on the line 8-8 of Fig.6 viewed in the direction of thearrow. Fig. 9 is a viowsimilar to Fig. 8 but on an enlarged scale andthe 9 door being shown in a closed position. Fig. 10 is an enlargedperspective viewshowing the mode of operating the dust-guard from thedoor.

Referring now to the drawings, 1 indicates 9 the door, 2 the framethereof and 3 the door sill. This door sill in the form of the inventionshown in Figs. 1 to 4 is preferably nar-. rowed onits inne side ed o,shown more clearly in Figs. 3 '4' 4, and is provided at 1 said innerside on its upper surface with a recess 4.

5'indicates a metal wear late, preferably of bronze, which islet in tot. e upper surface of the sill, and extends from end to end thereof,said plate projecting over the recess 4 and having its inner edgebeveled or rounded on opposlte sides as shown at 6. The upper s in faceof this plate is corrugated or roughened, as indicated at? except at theend portions xv. are a plain surface 8- is provided, one of which isshown in Fig. 2, and the other in Fig 7. in the space between the bottomof the recess 4 and the under side of the late 5, I interpose a feltstrip 9, which is ield in place by a rib 10 on the under side of theproecting portion of said plate, the plate 5 constituting one member ofthe weather-strip. The other member is carried by the door and isindicated by the numeral 11. Said member comprises a strip oflight-weight, pliable metal, such as zinc, which is bent upon itself torovide a curved projecting portion 12 having a hollow rounded edgeportion 13. One member of this strip projects outward over the curvedportion 13 and is indicated hp 14 and the other member, indicated by 15normally extends as shown by the full lines in Fig. 5 at more or less ofan obtuse angle to the member 14. The member 15 is of sufficient heightto ermit aportion thereof to be cut off asmay e necessary to make it runparallel to the lower edge of the door. That is to say, the bottomedgeof a door is frequently sprung outward at its lock edge and in applyingthe strip. 11 it is first placed against the lower edge of the door andthe edge portion 13 pushed inward until it comes in contact with thefelt strip. This necessitates the forward part of the strip at the lockedge, being placed farther in than that portion at the hinge edge of thedoor. The upper edge of the member 15, as shown by the netted lines inFig. 5, is now drawn inward and brought in contact with the lower edgeof the door and a line is drawn on. the strip from this point followingthe lower edge door line the entire length of the strip. This line isthen paralleled on the strip by another line to a distance of aboutthree-eighties of an inch nearer to the extreme edge of the member 15for a nailing margin, and the surplus strip is then cut away so that theupper edge of 15 will, when the members 14 and 15 are made fast to thedoor, as shown by Fig. 3, run parallel with the bottom edge thereof,with the first line exactly on the line of said bottom edge of the doorand permit sufficient extra width of the stri to extend downward andinward at an ang e so as to accommodate itself both to the outwardspring of the door at the lock edge and at the same time uniformlyongage with the felt- 9 and plate 5 with the rounded edge 13, theapplication of the member 14 to thebottom edge of the door ca sing theprojecting portion 12 to assume a position 'substantia y parallel withthe bottom edge of the door. This manner of procedure is renderednecessary by the fact that the adjustment and making fast of the member11 of the weather-strip must be done when the door is off its hinges andaway from the bronze plate 5.

At the front edge of the door, near the bottom hereof, secure a plate16, which is let into the wood so that its outer side will be flush withthe outer edge of the door, said eeaioe the front edge portion of thedoor as the latter is closed, and thus offset the slight sag of the doorwhich commonly occurs at this part. For this reason the rear end of theplate 16 is rounded at its bottom so that it will ride up the incline 6of the plate while the downward projecting portion 19 will rest upon thebeveled surface 6 in the closed position of the door. This slight liftof the forward edge portion of the door will also have a tonden cy tobring the rounded edge 13 of the member carried by the door in firmcontact with the under side of the plate 5 as more clearly shown by Fig.3. i

As thus far described it will be seen that the two members of myweather-strip cooperate Without friction to produce an air-tight closurebeneath the door. In addition, the felt strip acts in the manner of abumper to insure an easy or silent closing movement of the door.

It is frequently the case that the door sills are relativelyvery wideand the occupant of the house objects to having the same cut away at oneside in the manner shown in Fig. 3. Where the full width of the weather--strip is utilized the opening beneath the plate 5 at the inner side isrendered somewhat more pronounced in appearance and it is oftendesirable to close this space when the door is opened, not only toprevent access of dust and dirt beneath the plate 5, but to proventliability of said plate offering an 0bstruction to persons passingthrough thedoor. To this end, I provide a plate 20 which is pivotallymounted at its outeredge in metal blocks 21 located at the ends andcenter of the door sill, respectively, the free edge portion of saidplate being adapted to be raised into contact with the under beveledsurface of theplate 5 and to rest in a recess 20 provided in the sillwhen in its lower po; sition. V eye 22 at the inner end thereof andsecure on the inner edge of the door, in line with the T o raise thisplate I secure a smallhinge pintle, a rod 23 having its lower end formsas a spiral, as indicated at 24, and above this spiral having a straightportion 25. As the door is opened the spiral 24 engages the eye 22 andraises the plate 20, this raisin g of the plate, however, not beginninguntil the projecting member 12 of the strip carried by the door haspassedfrom under the inner edge of the plate 5. This lifting movementcontinues until the outer edge of the plate is along thebottom edconsisting of a metal plate bent and curved uponitself to'form,respectively, free edge brought into'engagement with the under side ofthe front edge of the plate when the straight portion of the rod 23engages the eye and holds the plate in this position. When the door isclosed the late or dust guard 20 is depressed by the spiral before theprojection 12 starts to enter beneath the plate 5. The raised positionof the dustguard 20 is shown in big. 8 and its lowered position in Fig.9.
